Multi-boot/Dual-Boot Windows XP on Windows 7

Installed first part of what?

Of XP. Read message, then post here.

At what exact point in the install does it fail?

What does the error message say in full?

The process is to google the error message and work through it.

Or try again and see if it repeats.

I have to replace the hal.dll file. Except I'm trying to get to Windows 7 to replace it. The computer I'm in doesn't have a card slot (Or haven't found one at least)

Missing Hal.dll - Missing Or Corrupt Hal.dll Error Message in Windows XP - Fix Hal.dll

I'd follow the steps here and as last resort do the repair install which it says can fix it.

In XP the repair install is done from booted installer, but not choosing "R" for repair at first, instead let it discover the installation and when it asks if you want to install there, THEN choose "R" for repair.

That's my problem. I can't access Windows 7 or Windows XP. It's only half installed, and I would have finished the installation if this computer I'm using had a Multi-Card Reader.

I do not understand the last resort part.

To boot into Win7, you need to access the Win7 Repair console to run Startup Repair repeatedly.

Try tapping F8 to see if there is a Repair my computer choice there.

If not, we will need to make you a bootable repair stick. What OS does your other computer have?

If you read the troubleshooting checklist for that dll error, the last step before reinstall is to run a Repair install. I was telling you how that is done. But you say now that it wasn't installed all the way, so there may be no XP installation found to repair.

This one is Windows Vista. And my last stick is a U3.

I told my dad for us to get a Multi-Card-Reader, then add the hal.dll file.

But if it's possible for me to get into Windows 7 right now just to download the file, let's try it.
